Which one to keep?!

I'm looking for some assistance on which of my two amps I should keep and which I should sell. I've mapped out the pros and cons but am still torn and hoping to gain some insight into the decision making process.

I'm mostly a solo basement player/hobbyist (in a house) but play with a drummer and/or another guitar player once a month or every other (so not often). I don't play very loud at home because I don't have a need to, and I have neighbors.

I have a 65 Deluxe Reverb Reissue with NOS tubes and a Cannabis Rex speaker. I love the way it sounds, fills the room (12'' speaker and bigger cab), and the Reverb response. I keep the Volume at 2.5-3 at home where it performs well but can shake the walls a bit. I never use the Normal Channel or Trem.

I also have a 72 Silverface Princeton Reverb with new tubes and the original CTS speaker. I got a pretty good deal on it and just had it recapped and brought up to snuff. I tend to play it more than the Deluxe because the volume is more manageable. I appreciate owning a piece of vintage gear and assume it will hold its value or even appreciate with time. I don't think it'd stand up to a drummer or another guitar player though, and it doesn't have the powerful Reverb or the "3Dness" of the Deluxe.

I want two amps, but I don't need two amps and I think I could get by with just one of them for my current needs. What say you?

I'd keep the DR but I've never owned one. I had the same predicament with my Twin and Princeton. The Princeton lacks the "3D ness" as you said and for that reason I had to let it go. The Twin filled the room and the Princeton while being a fabulous amp, just didn't do that job well.

@homesick345 brings up a valid point, but I would prolly still go with the DRRI. Nothing quite like it. The PR gets farty real early. I thought your self assesment was interesting. You don't play very loud at home because you don't have to and you have neighbors. On the other hand, I do play very loud at home even though I don't have to and I have neighbors. Easy for me to say, my wife and dog and neighbors like my playing as long as I'm not carrying on into the late hours of the night. I played my brother's PR for a summer and, although the clean sound was sweet, it was lacking in headroom, and as I said before, fahty.

If there isn't a real pressing reason, other than "I think I could get by with just one...", I'd keep both.

If you really do want to keep only one, I'd say keep the PR.
Put a more efficient speaker in it and it should do just fine for small jams.
Plus, if you decide later on that you really do need a DRRI, they're easy to find.

But that's me.

From your description, you like the DR better. Based on that alone, I'd recommend keeping the DR.
The bonus of that plan is that you'll be able to sell the PR for more than you would the DRRI.
Downside - a vintage PR is not as easily replaceable.

Hook the PR up into the Cannabis Rex speaker in the DRRI cabinet the next time you have one of your jams with your buddies. See if the PR holds up better with something other than the stock speaker (pretty sure it will).

Haa, I know three people who have gone through this exact dilemma including my best friend and mentor. Save yourself some time and money by just keeping both. These are both fantastic amps and pretty dang hard to beat. You will be chasing things that don't exist in the same way as these two amps provide, unless you start craving for some completely different amp voice or gig requirement. If I had the power (I live off the grid) these would be the two out of three amps I'd have for sure. FWIW.

So...when your ONE old amp needs repair, you're just gonna play acoustic?
If you don't really need the dough, don't do it.
ESPECIALLY before you daisy-chain them and see what they can do together.
2 amps is the bare-bones absolute minimum number of amps a gentleman (or lady) should own.
Would you drive without a spare tire?
Would you only want ONE friend?!?
CAN YOU EAT ONE POTATO CHIP?!?!?!?
For the love of God, COME TO YOUR SENSES, MAN!!!!!!!!!!
OK...I need to lie down.
